i have no idea how many bluetooth handsfree module exist in the world.
there must be many. actually the driver works for almost all BT
handsfree.
so my basic idea is making the codes as common as possible.

and i also want to add dt compatible in this driver, a generic
compatible string can be "bluetooth, handsfree", but users can add
specific string in its board dts like:

compatible = "delta, dfbmcs320", "bluetooth, handsfree";

so the driver will still work for  "delta, dfbmcs320".
